STAMPINGHMACHIN'E.

SPECIFICATION forming art of Letters Patent No. 632,548, dated September5, 1899.

Application filed February 3,1899. Serial No. 704,370. (No modeli) To(.LZZ whom it may concern:

Be it known that I, MAX E. BIERSACH, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State of\Visconsin, have invented new and useful Improvements inStamping-Machines, of which the following is a specification.

My invention relates to improvements in stamping-niachines,and pertainsespecially to that class of stamping-machines illustrated in connectionwith my former application, Serial No. 662,170, filed December 16, 1897,for machines for making antitacks.

The object of my invention is to provide means for stamping or printinglabels, with especial reference to that class of labels which arestamped or printed upon metal or other rigid surfaces.

In the following description reference is had to the accompanyingdrawings, in which- Figure 1 is a front View of my invention. Fig. 2 isa top view of the same. Fig. 3 is a sectional view drawn on line so a:of Fig. 1. Fig. 4 is a sectional view drawn on line y y of Fig. 1. Fig.5 is an enlarged detail view drawn on line U U of Fig. 1. Fig. 6 is arear View with the inking-pad and other parts removed to show theinterior construction of the vertical reciprocating printing-head, andFig. 7 is an enlarged detail view drawn on line T T of Fig. 6.

Like parts areidentified by the same reference-letters throughout theseveral views.

A bed-plate A is reciprocated horizontally underneath avertically-reciprocating printing-head 13, the latter being actuatedfrom the source of power by means of the belt 0, pulley G, eccentric D,adjustable connectinglink cl, and lever E. The motion of theprinting-head is communicated to the bed-plate through the springs F,rack-bars F, pinions f, shafts f, gear-wheels G,and horizontal rackbarsG. The printing-head is supported between and guided by the verticalposts H, and the die or printing plate I is supported underneath thehead by means of rods 1, which extend upwardly through guide-aperturesin the head, to which they are secured by means of springbuifers J. Theobject of the springs J is to permit sufiicient downward pressure toafiix the stamp and at the same time relieve the strain which would beexperienced if the printing-die were secured rigidly to the head.

In order to supply the'ink to the die or printing plate I, I haveprovided an inkingroller K, which is actuated from the head B by meansof the ears L, links L, ears M, crosshead M, lever N,androller-supporting forked arm N. The cross-head M is'su'pported upon arod 0, which connects'the supporting-posts H and forms afulcrum' for thelever N. The forked arm N is secured to the lever N by a hinged joint Pand by a connecting-spring Q, so that the inking-roller K will passyieldingly under the stamping-die I, one edge of which is curvedupwardly so as to receive the inking-roller on its under side.

R is an inking-pad supported from the posts H by the arms S,cross-barT,and springcushion U. I It will be observed that as theprintinghead B is moved upwardly its motion will be communicated throughthe connecting-links, cross-head, lever N, and forked arm N to force theinking-roller underneath the stamping-die I, while with'the reversemovement of the head B its movement will be communicated to swing, theinking-roller outwardly across the ink-pad R, from which it receives afresh supply of ink.

The operation of my device is as follows: The material to beprinted'upon is first placed upon the bed A, the printing-head B beingthen in its raised position, with the inkingroller K- underneath the dieI. \Vith the downward movement of the head B the inking-roller is swungoutwardly across the pad R, and the bed A is drawn inwardly underneaththe head B and die I until it engages a stop V in the rear of themachine underneath the inking-pad R, the head 13 being permitted tocontinue its downward movement by reason of the springs F, interposedbetween the head and the upper ends of the rack-bars F. The continueddownward movement of the head after the bed A is brought v in contactwith the stop V brings the die I into forcible contact with the materialupon the bed A, the springs J permitting the dieand the inking-rollerKis swung downwardly from the pad E into contact with the under surfaceof the die I. When the parts are in this position, the printed orstamped material may be removed from the bed A and fresh materialsubstituted, whereupon the opera tion of the machine is repeated, asabove described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination-of a vertically-reciprocating printing-head; a dieconnected therewith; a horizontally-reciprocating bed-plate; a stop forlimiting the inward movement of the bed-plate; and connections wherebysaid bedplate is adapted to be actuated from the printing-head.

2. The combination of averticalIy-reciproeating printing-head; a dieconnected therewith; a horizontally-reciprocating bed-plate; a stop forlimiting the inward movement of the bed-plate; and connections wherebysaid bed-plate is adapted to be actuated from the printing-head, saidconnections being provided witha yielding element adapted to permit theprinting-head to continue its move.-

3. The combination of a vertically-reciproeating printing-head; a dieyieldingly connected therewith; a horizontally-reciprocat= ingbed-plate; a stop for limiting the inward movement of the bed-plategandconnections whereby said bed-plate is adapted to be actuated from theprinting-head.

4. The-combination of a vertically-reciprocating printing-head; a dieconnected-there with; a horizontally-reciprocating bed-plate; a stop forlimiting the inward movement of the bed-plate; connections wherebysaidbed= plate is adapted to be actuated from the printing-head; and aninking roller connected with,and actuated from, said head, and adaptedto be swung alternately-into, and out of, contact with the surface ofsaid die.

In testimony whereof I aiiix my signature in the presence of twowitnesses.
